In the center of the scene, a vibrant green Lamborghini with a sleek, aerodynamic design zooms diagonally across the card. Its exaggerated, cartoonish wheels are comically large and bouncing as if caught mid-flight. Nearby, a robust Tesla Cybertruck with exaggerated angular lines and chrome glint, stands parked confidently, with a playful mix of cartoonish proportions, appearing ready for an adventure.

On the foreground, a whimsical birthday cake towers high, with at least five colorful tiers, each layer a different bold color—sunny yellow, electric blue, candy apple red, playful pink, and vibrant violet. Atop the cake, a Lego minifigure, sporting a wide grin, waves a tiny flag. The flag's fabric is creatively designed from Lego bricks, carrying bright primary colors with the name "Xavier" etched in large, bold, red block letters.

Scattered around the base of the cake are several Lego pieces, their iconic shapes instantly recognizable, adding playful texture to the scene. They are a mix of bright colors like emerald green, cherry red, sapphire blue, and lemon yellow.

In the background, a sky painted in a gentle gradient from warm peach to bright azure fills the top of the card, evoking a clear, sunny day. Puffy, cartoon-like clouds lazily drift across the horizon, some shaped like various iconic Lego pieces for a quirky twist.

A festive banner arches overhead, strung between two balloons that mimic the shapes of the Lamborghini and Cybertruck. The banner's letters are made to look like they are constructed from Lego bricks, with vivid colors like orange, purple, and teal.

Scattered confetti in myriad colors—magenta, lime, turquoise, and tangerine—float throughout the scene, adding a sense of lively celebration to this eclectic and exuberant birthday greeting card cover.
